I therefore tried different things and found that the problem was a 
misconfiguration of the RSS action. Thanks!

For future relevance, here is a working piece of code for RSS + MARK 
(+END) action :

     struct rte_flow_action action[3]; 

     struct rte_flow_action_mark mark; 

     struct rte_flow_action_rss rss; 


     memset(action, 0, sizeof(action)); 

     memset(&rss, 0, sizeof(rss)); 

 

     action[0].type = RTE_FLOW_ACTION_TYPE_MARK; 

     mark.id = _matches.size(); 

     action[0].conf = &mark;
 

     action[1].type = RTE_FLOW_ACTION_TYPE_RSS; 

     uint16_t queue[RTE_MAX_QUEUES_PER_PORT]; 

     queue[0] = 0;
     //TODO : enable all the queues of interest 

     uint8_t rss_key[40];
     struct rte_eth_rss_conf rss_conf;
     rss_conf.rss_key = rss_key; 

     rss_conf.rss_key_len = 40; 

     rte_eth_dev_rss_hash_conf_get(port_id, &rss_conf); 

     rss.types = rss_conf.rss_hf; 

     rss.key_len = rss_conf.rss_key_len; 

     rss.queue_num = 1;
     rss.key = rss_key; 

     rss.queue = queue; 

     rss.level = 0; 

     rss.func = RTE_ETH_HASH_FUNCTION_DEFAULT; 

     action[1].conf = &rss; 


     action[2].type = RTE_FLOW_ACTION_TYPE_END;

Thanks!
